Some of these pictures and descriptions may give away plot details that you might not want to know before watching the film.
This is at least the fourth big screen adaptation of Rudyard Kipling's classic book, and there may even be more than that. It uses a mix of motion capture and other digital effects and a live actor, the boy who plays Mowgli (Neel Sethi).
After Mowgli leaves the wolf pack that raised him to keep the tiger Shere Khan from harming the pack, he finds himself deep in the jungle where he sees a very large snake skin shed on the ground. Shortly after that he meets Kaa the python, (for the first time voiced by a woman - Scarlett Johannson.) Kaa seems to be hundreds of feet long as she hangs from several tree branches and talks to Mowgli very seductively, telling him his origin story which explains why Shere Khan wants to kill him and showing him a movie of what happened in one of her eyes. She slowly hypnotizes him as she wraps her coils around him and is about to kill and eat him when Baloo the sloth bear saves him and fights Kaa. We never see the results of the battle between python and bear, but we know Balloo is unharmed and, unlike other versions of the story, Kaa never appears again.
We also see a cobra at a water hole as we see all the different animals gathered there during a truce brought on by a drought.
